CONVEYER FOR WRAPPING AND LABELING MACHINES.

To all whom it may concern:

Be it known that we, NATE J. MATTHEWS, ROBERT Ln GRAND J OHNSTONE, andARTHUR \V. CASH, citizens of the United States, residing, respectively,at Newark, in the county of Essex and State of New'Jersey; Glen Ridge,county of Essex, and State of New Jersey, and Newark, county of Essex,and State of New Jersey, have invented certain new and usefulImprovements in Conveyers for rapping and Labeling Machines; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to characters of reference marked there on,which form a part of this specification.

The present invention has reference, generally, to improvements inautomatic conveyers for wrapping and labeling machines; and, thisinvention relates, more particularly, to an improvement in that class ofwrapping machines, such as are disclosed in previous applications forLetters-Patent filed, respectively, by Nate J. Matthews, January 28th,1909, Serial Number 474,699, and by Nate J. Matthews, Robert Le Grand Johnstone and Arthur W. Cash, as joint in ventors, July 30th, 1909,Serial Number 510,426.

The principal object of the present inven tion is to provide a novelconstruction of conveyer-device for said wrapping and labeling machinesadapted to receive the wrapped and labeled articles from the wrappingand labeling elements of the machine to convey the same to a receivingchute, from which they may be removed for packing in boxes, or for otherdisposal.

A further object of the present invention is to provide in connectionwith said conveyer-devices a novel means for driving the same, togetherwith means for adjusting or tightening the conveyer-belts which form apart of said conveyor-devices.

Other objects of the present invention not at this time moreparticularly mentioned will be clearly understood from the followingdetailed description of the said invention.

The invention is clearly illustrated in the- Speeification of LettersPatent.

Application filed November 5, 1909.

Patented Apr. 23, 1912.

Serial No. 526,342.

tion of the wrapping and labeling machine with which the novelconveyer-devices, embodying the principles of our present invention, areconnected. Fig. 2 is a longitudinal vertical section, taken on line 2-2in said Fig. 1; Fig. 3 is a transverse section, taken on line 33 in saidFig. 2, and Fig. 4 is a detail transverse section, taken on line 44 insaid Fig. 2.

Similar characters of reference are employed in all of the abovedescribed views, to indicate corresponding parts.

Referring now to the several figures of the drawings, thereference-character 5 indicates the framework of the wrapping machine inwhich are mounted the various operating devices and parts of saidmachine. Mounted in suitable bearings 6, which are suitably connectedwith said framework 5, is one of the wrapping-rollers, in this case thelast or label-roll 7, the same being provided with the transverseopening or slot 8 in which is slidably arranged the push-device or element 9. Elevated and secured upon studs 10, which are suitably disposedupon and se cured to the frame-work 5, is a horizontal plate or platform11, upon the upper surface of which are arranged and secured a pair oflongitudinally extending guide-members 12. The ends of said uide-members12, adjacent to said label-roll are provided with downwardly extendingportions 13, and journaled in the upper portions of said downwardlyextending portions 13 is an idler-roller 14. In a like manner, journaledin the lower portion of said downwardly extending portions 13, isanother idler-roller 15. The said idler-rollers 14 and 15 arerespectively just above and below the mouth of the opening or slot 8 insaid label-roll 7 when said opening or slot is in its horizontalposition ready for the delivery of a wrapped and labeled article.Secured in any suitable manner, so as to extend across the top surfacesof said guide-members 12, is a top-plate 16. Secured upon the undersurface of said plate or platform 11 are a second pair of guide-members17, and secured in any suitable manner, so as to extend across the undersurfaces of said guide-members 17, is a bottom-plate 18. Secured to theunder surface of said bot-tomplate 18, in any suitable manner and in theproper location, are a pair of bearingbrackets 19, and journaled in saidbearingbrackets 19 is an idler-roller 20. Mounted in said frame-work 5of said wrapping and labeling machine is a transverse shaft 21, andpivotally mounted upon said transverse shaft 21 is a frame-member 22which is provided at each end adjacent to the inner sides of theframe-work 5 with a pair of upwardly extending arms 28. Journaled in theupper end of said arms 23 is a shaft 24 upon which is secured a drivingroller 25. Said shaft 24 is further provided with a gear-wheel. 26secured thereto. Suitable collars 27 are arranged upon said shaft 24 toretain the ClllVlIlg-l'OllOl' 25 in proper alinement. In like manner,here is journaled between said arms 28, at a point below the shaft 24, adriving shaft 28 said shaft 28 projecting outwardly at one end beyondthe frame-work 5 and having secured thereto a pulley-wheel 29 which isconnected by means of a belt 30 to the main driving shaft of thewrapping and labeling machine. Secured upon said drivin shaft 28 is adriving pulley 81, adjacent to one end of which is a gear-wheel 32 whichmeshes with a gearwheel 26 secured upon said shaft 24. Suitable collars83 are arranged upon said driving shaft 28 to retain said driving-rollerin proper alinement. Formed integrally with said frame-member 22 andextending downwardly therefrom is a tongue or lug 34 in the free end ofwhich is arranged a set-screw 35, the end of which bears against asuitable seat 36 formed in a portion of the framework 5 of said wrappingand labeling machine. Extending from the driving-roller 25 and aroundthe idler-roller 14 is an endless belt 37, the lower side of whichpasses between the guide-members 17 and directly beneath the undersurface of said plate or platform 11; and the upper side of which passesbetween the guide-members 12 and above the said plate or platform 11. Inlike manner, extending from the driving pulley 31 and around theidler-roller 15 is an end less belt 38, the upper side of which passesbetween the guide-members 17 directly above the bottomplate 18, and thelower side of which passes beneath said bottom-plate 18 and over theidler-roller 20. Arranged at the discharge end of said endless belts 37and 38 is a receiving-chute 39, the same being supported by ayoke-member 40 which is secured there-to, said member being providedwith a pair of straddler-arms 41, which are formed at their free endswith forked-members 42 which operatively engage the driving shaft 28substantially as shown. As a further means for properly supporting saidchute 39, there is secured in the base-member 43 of said frame-work 5 astud-screw 44, the free end of which is in supporting engagement withthe yoke-member 40 of said receivingchute 39, said stud-screw beinglocked in a proper adjusted position by means of the nut 45.

The operation of the c0nveyerdevices, the construction of which hasabove been set forth in detail, is very simple. The drivingpulley 29imparts motion to the driving shaft 28 and driving-roller 31 whichcauses the proper operation of the endless belt 88, and the gear-wheel32 transmits its motion to the gear-wheel 26, shaft 24 and drivingroller25, whereby the belt 37 is properly operated. As the wrapped and labeledarticle is discharged from the slot 8 of said labelroll 7 it is receivedbetween the moving belts 37 and 88. The belts 37 and 38 keep the freshlygulnmed label and wrapper in place as the article is squeezedtherebctween, so that while the said belts convey the articles on towardthe receiving-chutes sufficient time elapses to allow the gunnned labeland wrappeer to dry securely in place. ltlventuall y the w 'apped andlabeled article passes through the dischar e-end of said belts 37 and 38and into said receiving-chute 39. Said receivingchute 39 is furtherprovided at its receiving end with a suitably mounted idler-roller 46,the same serving to facilitate the movement of the wrapped article intothe chute as it passes from the discharge end of the moving belts. Thesaid idler-roller 46 reduces the friction, and also prevents a wrappedarticle from catching or tripping before the same is finally depositedin proper position flat upon the floor of said receiving-chute.

The belts 37 and 38 are kept in av proper condition of tautness by theoperation of the set-screw which, bearing against the basemember 48,pushes the tongue or lug 34 outwardly and carries forward the upwardlyextending arms 23 of said frame-member 22 which is pivotally mountedupon said shaft 21. The outward movement of said arms 3 carries withthem the driving-roller 31' and drivingroller 25 thus exerting atightening pressure upon said belts 87 and 38. The said receiving chute39 being supported by said yoke-member 40, which by means of itsstraddler-arms 41 and forked members 42 engages the shaft 28, istherefore maintained at a constant proper receiving relation to thedischarge end of the said endlessbelts which form the conveyer. Thispivotal connection between the said receiving-chute 39 and the shaft 28permits of the adjustment of the tension of said endless belts throughthe movement of said frame-member 22, as above described, withoutdisturbing the receiving relation of said. receivingchute thereto, sincethe same will move in correspondence with the movement of said shaft 28as controlled by the movement of said frame-member 22.

V fe are aware that changes may be made in the general arrangements andcombinations of the various devices and parts, as well as in the detailsof the construction of the same without departing from the scope of ourpresent invention as set forth in the foregoing specification and asdefined in the appended claims. Hence, we do not limit our invention tothe exact arrangements and combinations of the devices and parts asdescribed in the said specification, nor do we confine ourselves to theexact details of the construction of the said parts as illustrated inthe accompanying drawings.
